in unicellular organisms, what makes up the organism

Answer:

The correct answer is - lower

Explanation:

Pregnant women require an increased amount of calcium as it can provide a sufficient amount of calcium for herself and her fetuses. During lactation, the calcium is reabsorbed very fast and rapidly that supplies the calcium for the milk. So, the normal women of childbearing age do not require the amount of calcium as pregnant women require.

Thus, there is a lower absorption rate of calcium as compared to a pregnant women

Answer:

Leaves are always the color they turn in the fall

Explanation:

The chlorophyll created when the leaves use sunlight to create energy for the tree has a green pigment that covers the leaves actual colors. As the leaves separate from the trees they stop making chlorophyll, thus allowing the leaves true colors to return.

I hope this helps and good luck on that two-pager!

Answer:

During the fall the day gets shorter hence less sunlight this results to leaves stopping their food making process. The chlorophyll breaks down, the green color disappears and the yellow to orange color becomes visible

Answer:

Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

Answer:

Phosphate group is the structural difference between triglycerides and phospholipids. A triglyceride contains three fatty acids attached to the glycerol backbone whereas a phospholipid has two fatty acids and a phosphate group attached to the glycerol.

Answer:

There are specific receptors present on the surface of the normal cell membrane to recognize the molecules to allow them to pass or not. Most of the bacterial toxin are water-soluble molecules, and bound to the cell surface and interact with them as some time antibody-antigen interaction or cell recognition does not occur that form a pore in the cell membrane and toxins move into the cell.

Once toxins enter the cell they attack intracellular targets through endocytic vesicles. Ultimately these ends in cell death.

The cells are not able to stop the flow of the mentioned harmful substances into the cell as they fail to recognize them as foreign entities. These foreign toxins have intracellular targets with which they bind and lead to death of the cell.

The plasma membrane is formed of lipids. The toxins produced by the bacterial cells are water soluble. Therefore, they identify particular receptors on the membrane and associate with them. Thus, cell at certain occasions fail to identify them as foreign entities.

They combine with the plasma membrane of the cell and induce pore formation, however, there are many toxins that invade the cell and possess intracellular targets via endocytic vesicles. With the help of these vesicles, they deliver their enzymatic domain into the cytosol and results in the death of the cell by obstructing the metabolism of the cell.

Thus, cells fail to identify the bacterial toxins as foreign entities and they invade the cell and results in cell death.

Answer:

Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources (see also mineral resource classification). Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. The value of a resource is a direct result of its availability in nature and the cost of extracting the resource, the more a resource is depleted the more the value of the resource increases. There are several types of resource depletion, the most known being: Aquifer depletion, deforestation, mining for fossil fuels and minerals, pollution or contamination of resources, slash-and-burn agricultural practices, Soil erosion, and overconsumption, excessive or unnecessary use of resources.

Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and consumption of fossil fuels. Depletion of wildlife populations is called defaunation.

Answer:

Answer is A. Diffusion

Explanation:

Because diffusion is a passive process in which a substance moves from a higher concentration to a lower concentration until the concentration becomes equal

The passive movement of particles from a region of higher concentration to a region of lower concentration is known as diffusion. Thus, the correct option is A.

Diffusion may be defined as the passive movement of particles from a region of higher concentration to a region of lower concentration.

Active transport requires energy for the movement of particles. Selective permeability may be defined as the ability to differentiate the movements of different types of particles in and out of the membrane.

Therefore, the correct option for this question is A.

After 2000 years, there will be 5g of the isotope remaining.

If an isotope has a half-life of 1000 years, it means that after 1000 years, half of the original sample will have decayed. After another 1000 years (2000 years total), half of the remaining sample will have decayed, and so on.

To calculate how much of the sample will be left after 2000 years, we can use the following formula:

[tex]N = N_{0} * (1/2)^ (t/T)[/tex]

where:

N = the amount of the isotope remaining after time t

N0 = the initial amount of the isotope

t = the time that has elapsed

T = the half-life of the isotope

Plugging in the values from the problem, we get:

N = 20g * (1/2)^(2000/1000)

N = 20g * (1/2)^2

N = 20g * 1/4

N = 5g

Therefore, after 2000 years, there will be 5g of the isotope remaining.

Answer:

A

Explanation:

All of the other options are specific to water, but quite a few liquids cool off a lot faster than water.

water cools very rapidly is not a unique property of water. Thus option A is correct.

It has no taste, odor, or transparency, where the nucleus of the oxygen atom  attracts electrons strongly than the nuclei of the hydrogen atoms.

In water molecule oxygen is more electro negative and electron-greedy than hydrogen, results in the development of  a partial negative charge on the oxygen of the water and a partial positive charge on the hydrogen end.

Water shows strong cohesive property where the attraction of molecules for other molecules of the same kind is referred to as cohesion.

Surface tension is defined as  the tendency of  the surface to resist rupture when they are subjected to stress due to cohesive forces.

D) water covered most of the earths surface and retains a large amount of heat

Answer:

There are two primary factors: size and distance from the Sun. Gravity helps planets and moons to hold on to their atmospheres, so small planets/moons such as Mars and the Moon have thin atmospheres. The reason why the outer planets are larger is probably down to two major factors. The first is simply the amount of material available which may be accreted to a planet. Clearly, the further away from the Sun, the longer the orbit (twice as far means an orbit twice the physical length).

Answer:

It is possible for their children to either have widow's peak or a smooth hairline.

Explanation:

Let's say that the widow's peak allele is W (dominant) and the smooth hairline is w (recessive).

A woman heterozygous for widow's peak is Ww. A man with a smooth hairline must have two copies of the smooth allele since it is a recessive trait, so he must be ww.

The cross is Ww x ww

                    W               w

    w            Ww            ww

    w           Ww           ww

There is a 50% chance that the children will have the genotype Ww, and therefore have a widow's peak. There is a 50% chance the children will be ww, and will therefore have a smooth hairline.

So, It is possible for their children to either have widow's peak or a smooth hairline.
